ABBA reunited - for a moment

The original stars of Swedish pop quartet Abba have reunited for the home premiere of hit musical Mamma Mia! which is based on the band's songs. It is first time in almost 20 years that the four, Bjorn Ulvaeus, Benny Andersson, Agnetha Faltskog and Anni-Frid Lyngstad, have met publicly. During their eight years together, Abba sold more than 360 million albums, including nine British number-one singles, becoming Sweden's second biggest export after Volvo cars. Such is their enduring appeal that they still shift more than 3,500 CDs a day. The musical, which has become a global phenomenon, will be performed in Swedish for the first time. More than 20 million people around the world have seen the show.
